Emotional robot (image 1 of 2). Male researcher standing with the emotional Lego robot which he designed and built. The robot is equipped with a Mindstorm (not seen), a programmable Lego brick. The Mindstorm is programmed to make the robot react to its environment, either showing a happy (as here) or sad face. The stimuli which the robot reacts to could be light, touch or temperature. Sensors will detect these stimuli and the Mindst- orm will then calculate the appropriate facial response. The user is challenged to find out what makes the robot smile. Photographed at LegoLab, Aarhus University, Denmark. See photo T260/088 for an image of the robot with a sad face.
